You're already renting out your bedroom, volunteering for a wristband, trading your SS# for tallboys, and boning musicians who just want someone who'll leave in the morning. Here's one more way to monetize SXSW: ParkatmyHouse. ATX-debuting in March, the Brit-born web service & mobile app connects drivers with unused residential/business parking spots while earning cash for the space-provider, and totally ruining his hopscotch tournament. How it works:
To rent square footage, plug your address into their online widget to get a rough estimate of your concrete's value, name your asking price, and either set a window of availability or choose Instant Booking (lets drivers mosey on over w/o prior approval), then just wait for the bucks to come rolling into your PayPal, especially if one of them is Glenn Robinson and his $68,000,000 rookie contract.
If you're so desperate to park you actually wish you were handicapped, credit-card-reserve a spot from a geographical display of avail spaces complete with prices and photos, so you can scour 'til you're certain your ride will star in a "kid trampolines into Merkur XR4Ti" video.
To make you feel better about your greed/need, ParkatmyHouse references a study stating that 1/3 of urban auto emissions come from drivers aimlessly looking for a parking spot -- so the planet will be the same color as the money you earn, and that bass player you totally ditched to get down with the drummer.
